仿照N.C.Hopkins文章[3]中的幂零定义,给出一种与N.C.Hopkins及Noriaki Kamiya的定义方法均不相同的定义方法(最后证明,事实上这种定义的方式在本质上等价于Noriak Kamiya的定义方法[2]).更重要的是,在Noriaki Kamiya的定理3的证明[2]过程中存在着明显的不完善之处,这里作者利用新的方法定义了一种完善而且简洁的证明.
Mimicking Hopkins's definition of nilpotence[3],the author gives a different method of definition of nilpotence which is equivalent to that of Kamiya[2].What's more,the proof of Kamiya's Theorem 3 is incomplete;here the author gives a complete precise proof.
